4Pcs 50ml/1.69 Oz Clear Refillable Glass Roll-On Deodorant Bottles Reusable Leak-Proof Massage Roller Bottles Containers with Roller Ball and Black Cap for DIY Deodorant, 3ml Transfer Dropper

ONLY bad thing I have to say is the caps do break. Beware and do not overtighten even a little bit.

Good review! Used for natural deodorant mixes. They work ok, might leak a little sometimes-- I am happy overall! Open with a sharp paring knife and twist. My fav recipe so far is: 1/2 cup boiled water, 1/2 tsp baking soda, 1/4 tsp magnesium flakes. Shake to mix. Dust on baking soda or arrowroot powder afterwards for extra security. Be careful with essential oils under your arms because they can cause stress on your system, even just one drop!!!!

These are good the only issue I have is the lids keep cracking even keeping it loose they break very easy. The bottles are very well made also the roller ball would be better if they were metal cause of the leaking issue. I hope they come up with a better cap & roller ball. Other then that I use them no problem & my customers haven’t complained yet with the product I make I let them know ahead of time the lid may crack. Eventually I would get a better made bottle.

The media could not be loaded.  Esta botella definitivamente ya la he comprado varias veces puesto que yo me dedico a elaborar desodorantes naturales y pues bueno pues estar completamente seguro que el líquido está muy bien dentro y no escurre para nada

The bottle caps are made of a thin plastic which cracks after a few uses. Some of the rollers do not roll well. The seller does not offer any kind of replacement option. Will also not work for travel as they leak.
